text: Parts of the Mariana Trench in the Pacific Ocean are up to 11 kilometres deep, so we know little about what sea life there is.
  So a team has been sending down a robotic submarine called Deep Discoverer with a camera on it.
  Science fans or anyone who is just curious can check out what the camera is showing online.
  The three-month expedition is looking for things like fish, mud volcanoes and deep sea coral.
  So far they've spotted shrimp, jellyfish and black pillow lava from an underwater eruption.
target: Scientists are exploring the deepest place on Earth - and streaming live video from there.
